Abstract

Une lampe à incandescence, en particulier une lampe à halogène (9) comprenant une ampoule (10) symétrique en rotation et un revêtement (14) réfléchissant le rayonnement IR, présente un profil partiellement ellipsoïdal. Le profil partiel ellipsoïdal de l'ampoule est obtenu par une section en ellipse, dont le petit demi-axe est perpendiculaire à l'axe longitudinal, c'est-à-dire est orienté perpendiculairement à l'axe de rotation de l'ampoule (10) et est supérieur au plus grand rayon R de l'ampoule. De préférence, la longueur du petit demi-axe b se situe dans la plage R < b < R + 5 . wr, où R et wr désignent, respectivement, le plus grand rayon de l'ampoule (10) et, le rayon de l'élément lumineux symétrique en rotation (15). En plus d'un accroissement du rendement, la lampe (9) est caractérisée par une rétroréflexion uniforme du rayonnement IR sur l'élément lumineux (15) disposé au centre, axialement, à l'intérieur de l'ampoule (10) et, de ce fait, par une répartition uniforme de la température.
